By focusing at collecting [item=118100] for rep, you should be able to get to exalted in around 2 hours if you start out as honored.
By going for chest's and ignoring the rares (unless they are almost dead), you can easy collect 15-25 [item=118100] on a quick round, the chest's will also grant you some [item=118099] which you can turn in as well.
The [item=118100] stacks to 20, while [item=118099] stacks to 100, so you might want to clear your bags as well, to fit them if you want to take more than 1 round.
I suggest when you have taken one round that you get invited into group, to get transported to another server, then the chest's are likely to be up again for you there.
The locations on the chests ([object=237227]) can spawn on following locations (might not be a complete list) - split up in 4 macros for tomtom addon:
